Argonne’s METL gears up to test more sodium fast reactor components
Argonne National Laboratory has successfully swapped out an aging cold trap in the sodium test loop called METL (Mechanisms Engineering Test Loop), the Department of Energy announced April 23. The upgrade is the first of its kind in the United States in more than 30 years, according to the DOE, and will help test components and operations for the sodium-cooled fast reactors being developed now.

A program was carried out to develop small less fragile ceramic electrodes for use in measuring oxygen in sodium. To use the electrodes as inserts in existing sampler hardware, composite metal-ceramic tubes were required. Four configurations of composite metal-ceramic probes employing yttria-doped thoria as the solid electrolyte were fabricated and tested. These incorporated both mechanical and brazed seals between the metal and ceramic. The most useful for fast flux test facility applications utilized a brazed seal between the ceramic and an alloy of matching coefficient of thermal expansion. A number of alternate reference systems were also investigated. Reference electrodes tested included Na-Na2O, In-In2O3, Ni-NiO, and Ag-air.
